How can I get this script to loop X amount of times? - loops

Question

I am trying to loop everything under groupadd coffee for 5 times for creating 5 new users at a time. Taking those variables and filling in the other commands. After all that is finished start again for a new user. I've searched up and down and can't seem to figure it out. Here is the script:
#!/bin/bash
#Script for adding users and groups
if [ $(getent group Coffee) ]; then
echo
else
sudo groupadd Coffee
fi
read -p "What is the new user's login ID? " username
read -s -p "What is the user's password? " password
echo
read -p "What is the new user's full name? " fullname
read -p "What is the new user's initial group? " intgroup
read -p "What is the new user's additional group? " addgroup
if [ $(getent group $intgroup) ]; then
echo
else
sudo groupadd $intgroup
fi
if [ $(getent group $addgroup) ]; then
echo
else
sudo groupadd $addgroup
fi
sudo useradd -m -G Coffee,$intgroup,$addgroup $username
if [ -z $password ]
then
echo -e "newpass\nnewpass" | sudo passwd $username
else
echo -e "$password\n$password" | sudo passwd $username
fi
I know I may have to restructure this but I am hoping it is something simple I can add to fix it.

Here is the solution that I got helped with.
<pre>
#!/bin/bash
sudo groupadd Coffee
# adds group Coffee to system
COUNTER=0
while [ $COUNTER -lt 5 ]; do
echo The counter is $COUNTER
echo
read -p "What is the new user's login ID? " username
read -s -p "What is the user's password? " password
echo
read -p "What is the new user's full name? " fullname
read -p "What is the new user's initial group? " intgroup
read -p "What is the new user's additional group? " addgroup
#prompts for variables
if [ $(getent group $intgroup) ]; then
echo
else
sudo groupadd $intgroup
fi
#checks to see if specified group is on the system
if [ $(getent group $addgroup) ]; then
echo
else
sudo groupadd $addgroup
fi
#checks to see if specified group is on the system
sudo useradd -m -G Coffee,$intgroup,$addgroup $username
#creates home directory and adds user into groups
if [ -z $password ]
then
echo -e "newpass\nnewpass" | sudo passwd $username
else
echo -e "$password\n$password" | sudo passwd $username
fi
#changes password or gives default one
let COUNTER=COUNTER+1
done
echo
